IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 216,968, dated July 1,1879; application filed December 16, 1878.

a'draw-bar head in such a manner that the' link can be held at anyrequired position for coupling, and the coupling-pin held in position todrop into the link when one draw-bar comes in contact with another.

My invention consists in the new construction and arrangement of thelink-chamber and pin-holes of a draw-bar head, and in the newcombination of parts, as will be hereinafter fully described and setforth.

In the accompanying drawing, my newlyconstructed draw-bar is representedby a single longitudinal sectional view, in which A represents thedraw-bar, having the linkchamber 13 in the head.

i The mouth of the chamber B is of the ordinary construction-i. 0.,flaring from the end to the pin-holesso as to permit the link to beadjusted sidewise, up or down, as may be required. The rear part of thelink-chamber is curved or inclined downward, as shown at D. The upperpart of the curved chamber D is provided with notches f f f f*, forholding the inner end of the link Gin various positions, as shown. Thecurved part f at the bottom of the link-chamber forms a fulcrum back ofthe pin-hole for the link 0 to rest on. Thus the link 0 is supported andheld at any desired angle, as shown at O 0 O The pin-hole 0 0 isofpeculiar construction,- to wit: The upper hole, 0, is provided with aninward-projecting lip, b, at the top and rear side, which forms asupport for the pin E, as shown. The lower front inner edge of the hole0 is also provided with an inward projection, (I, on which the lower endof the pin E rests, as shown. The lower hole, 0, is provided with aflaring upper end, P, to guide the end of the pin into the hole 0 whensaid pin is dropped through the link.

The pin E may be provided with the notch a to fit over the projection b,as shown or the notch a may bedispensed with.

The operation of my improved device is as follows: The link 0 is firstplaced in the chamber B, and the rear end placed in any one of thenotches that will hold the link in its proper position for making thecoupling. The pin E is then inserted in the hole 0, with its lower endresting on the projection d, or the notch a hooked on the projection b.The link and pin are then in position to make a coupling, and when thedraw-bar strikes another the link enters the other chamber, and theconcussion causes the pin to drop through the link into the hole 0.

The pin E may be set in the position shown in the drawing, and the linkbe held in the opposite draw-bar, so, that when the link en ters theempty chamber the pin will drop through the link and make the coupling.

What I claim as new, and desire to secure by Letters Patent, is

1. The draw-bar A, having the link-chamber B, with the downward curvedor inclined part D, when said part D is provided with notches f f f f inits upper side, and curved fulcrum f at the bottom, back of the pin-holeO, substantially as shown and described.

2. The draw-bar A, having the link-chamber B, with downward curved orinclined part D, provided with notches f f f f fulcrum f, and pin-hole0, when said pin-hole is .provided with an inward-projecting ledge, d,at the lower inner edge, substantially as shown and described.

3. The draw-bar A, having the link-chamber B, with downward curved orinclined part D, provided with notches f f f f above and the fulcrum fbelow, and the pinholes O 0, when the hole 0 has a ledge, d, forsupporting the pin, and the hole 0 is provided with a flaring mouth, P,substantially as shown and described.

In testimonywhereof I have signed my name to this specification in thepresence of two subscribing witnesses.

B. G. PAINE.
